Abstract: 194,794. British Timken, Ltd., and Ellis, L. M. Dec. 17, 1921. Separating and sorting gauges.-Apparatus for grading or gauging rollers or balls for bearings or other articles comprises a holder for the articles and a gauge plate to either of which a relative r.eciprocating or sliding movement is imparted the arrangement being such that an inclined edge on the gauge plate causes the article to be wedged between it and the holder so that further relative movement of these parts is prevented whereupon at the end of the movement the article is positively ejected into the appropriate one of a series of shoots. Automatic feeding means is provided to feed the rollers singly to the holder. Various sections of a machine for sorting taper rollers are, shown in Figs. 4, 5 and 6. The machine comprises a reciprocating member 1 actuated by a crank 4, slotted link 5 and connecting rod 72; the upper face of the member 1 is channelled at 6 and to one side thereof is fitted an adjustable gauge plate 7 with projections 14 overlying the channel in vertical alignment with holes 16 in the base of the member 1 and inclined to the path of movement of the said' member. The inclination of the plate is adjusted by screw pins 10 and is held in set position by bolts 8 passing through slots 9 therein. Projections 15 and 20 are provided at the extremities of the gauge plate 7 for the purpose of rejecting rollers of larger or smaller diameter than the grades required. The rollers, fed from an automatic feeding device 54, are received on a grooved locating block 21 secured to the frame of the machine by a screwed rod 23; in the chan. nel 6 alongside said block is a supporting block 25 to which is bolted a V-gap roller holder 26 which are normally held stationary by a spring friction clip 29 secured to the frame work and engaging a pin 30 on the block 25. The locating block ensures the gauge plate engaging the rollers at a constant distance from their larger diameter and in operation when the reciprocating member moves to the right in Fig. 4, the gauge plate 7 moves relatively to the holder 26 until the roller 34 becomes wedged between it and the gauge plate whereupon the holder is released from its clip 29 and moves with the member 1 until at the 'end of the movement the holes 16 are, in register with a corresponding series of shoots 35 terminating in suitable containers 36. The rollers are positively ejected by means of a spring controlled bar 65 having inclined slots 67 engaging bolts 66 on the framework and which is provided with a lateral pin 71 adapted to be engaged near the end of the movement of the member 1 by a pin 69 mounted thereon. The feeding device comprises a housing 54 which has an aperture in its top communicating with a feed tube 57 and an aperture in its base out of alignment with the former aperture and arranged above the roller holder 26. A spring operated sliding block 59 with a vertical passage 61 is arranged in the housing 54 and is provided with a lateral pin adapted to be engaged by a vertical pin on the member 1 which engagement takes place just prior to the member 1 reaching its normal left hand position Fig. 4 so that a roller in the passage 61 drops on to the locating block 21. The return of the holder 26 to initial position for engagement with the spring clip 29 is effected by a screwbolt 37 mounted in a plate secured to the reciprocating member 1 and adapted to engage the supporting block 25. Instead of mounting the reciprocating member on rollers it may work in grooves or guides in the bed of the machine. In a modification the gauge plate may be fixed and the roller holder carried on the reciprocating member.
